HYDRANT.

Application filedflctober 19, 1925. Serial No. 63,388.

My present invention relates to improvements 1n hydrants for use in supplying and distributing water for fire control systems and adapted especially for use in municipah ities on streets or highways. The primary object of the invention is to improvehy drants now in use and utilizing a plurality of ports for the hydrant including a main port for. connection with a power pumping engine, together. with auxiliary portswhich may be used before the power pumping engine is coupled with the hydrant. 'The auxiliary ports are under control of a rotary valve accessible for operation from the exterior of the hydrant. By constructing the hydrant according to the principles of my invention essential time maybe saved in preparing to fight a fire by first utilizing the auxiliary ports to supply. one or more streams of water while the connection is being madeto the hydrant for the main hose line to the power pumping engine. Means are provided whereby the position of the ports of the rotary valve may readily be ascertained; means are provided forv retain ing the valve in adjusted position, and other meritorious features and accessories are embodied inthe present invention as will hereinafter, be set forth. The invention consis s in certain novel combinations and arrangements of parts for the above indicated purposes as will be pointed out in my. appended claims.

In the accompanying drawings I have illustrated one complete example of the physi cal. embodiment of my invention wherein the parts are combined and arranged according to one mode I have, thus far devised for the practical application of the principles of my invention.

In carrying .out my invention "I have adopted a well known style or pattern of hydrant now in use, which is usually provided, with an elbow or casting 1 located underground and connected with the watermain. The hydrant as herein illustrated comprises a shell orhollow casing made up in sections 5 as 2 for the 'base,,3 the cylinder, and 4: the head of the hydrant. 7 These sections are cast as separate members andthey are provided with annular attaching flanges 5 and secured together with bolts 6 in suitable man ner in order that access to the interior'of the hydrant may readily be had when necessary and to assist in assembling the parts.

A. main reciprocating valve 7 of usual type is located. in the lower part ofthe hydrant i to control admission of water thereto from the water main, and this valve is normally closed indicated in the drawings. The valve is vertically movable and'cooperates with a valve seat 8 from which it may be vithdrawn through movement imparted to itsstem 9 that projects upwardly into the hydrant. A non-rotary spider frame 10 is.

coupled or fixed on the stem and moves bodily with it to guide andstabilize the valve in its opening and closing movements as it is lowered or raised.

Above the reciprocating valve and fashioned in the cylinder section 3 is a main port 11 that is normally closed by a cap 12 havinga nut portion 13 for the application thereto of a wrench when uncovering the port for connection of the main hose line of a pumping engine. This main port is unobstructed, except for the closure cap and after the reciprocating valve is opened water may be withdrawn through the applied hose line. in usual manner., v I a In addition to the main port a plurality of auxiliary ports 14 and 15 areprovided in the cylinder 3, said ports prefinably being locatedin the walls of the. cylinder and spaced at an angle of 90 as indicated-in Figure 4t. These ports are normally closed. from the exterior by caps or closures16 and 17 screwed on the threaded bosses of the ports in manner similar to the'cap of the main port. v V Y I The auxiliary ports are controlled from theinte-rior of the hydrant by means of a hollow, rotary valve 18 which is fashioned with ports 19 and 20 adapted to register with the ports 14 and 15 respectively. of the cylinder thatencases the valve.

. valve.

The rotary valve is preferably fashioned with an enlarged head 21 at its lower open end and bronze packing rings are used in the head to insure a water tight joint but permit rotation of the valve when required. At its upper end the hollow valve is fashioned with a flanged head 22 which is seated in an annular groove 22 provided therefor in the upper end of the cylinder 3 as a hearing for thevalve. The valve stem 23 is shown as hollow and it is fashioned with a nut portion 24 exterior of the hydrant and an annular bearing flange 25 also exterior of the hydrant and adapted to trictionally engage the bearing face 26 on the reduced portion of the head 4 of the hydrant. By means of a suitable wrench applied to the nut 24 it will be apparent that the valve may 7 be turned within its cylinder or cylindrical casing to regulate flow of water through both its ports 19 and from the interior of the hydrant and through the complementary ports 14 and 15 of the cylinder or casing. Thus water under the regular main pressure may be obtained from the hydrant by use of either or both of the ports 14 and 15 For indicating the position of the valve two pointers 27 and 2 1 are utilized on the flange of the nut 24:, which, as seen in Figure 3 point to. the axial lines of the respective ports 14 and 15 or 19 and 20 when the pair of auxiliary ports are open, and are arranged in fixed relation to the valve ports for indicating their positions.

The main reciprocating valve 7 is also manipulated from the exterior of the hydrant, through an operating rod 28 alined.

with the valve stem 9 of the reciprocating valve. This rod isfashioned with a nut or head 28 exterior of the hydrant for use with a wrench, and at its lower endwithin the hollow rotary valve the rod is fashioned with an interiorly threaded head 29 that engages complementary threads on the upper end of the valve stem 9. The rod extends downward through the valve stem 23 and the head 29 is retained in a guide ring or spider frame 30 which is rigidly retained within the cylinder and below the valve 18. A spring 81 is interposed between the frame 30 and a flange or other abutment 32 on the lower end of the threaded head 29 for holding (the threaded head in position.

The upper end. of the valve rod 28 is journaled; in a lock nut 33 having exterior threads and screwed into thc open upper end of the hollow valve stem 23, and. packing material 84 and a gasket 35 are used in con nection withthe lock nut 36 on the valve rod for securing a water tight joint which joint however: is sufliciently loose to permit relative movement of the-rod 28 and the rotary In Figure 5 a spring pressed detent 37 is indicated as carried at the underside of the flange 25 of the hollow valve stem, and this detent is designed to engage one of the depressions or sockets 38 of the bearing face 26 on the hydrant head 4.

It will be apparent, from this description that with a wrench applied to the head 28 the valve rod 28 may be turned, but maintained against longitudinal movement, and that the co-action of the threaded head 29 with the threaded end of the valve stem 9 will cause the valve 7 to be unseated or seated as desired. In order to restrict flow of water to port 15 the valve is turned to bring opening 19 to register therewith, while to limit the flow of water to the port 14, the valve is turned to the right to bring opening 19 to register with port 14.

It will be noted from Fig. 2 that the ratary valve of my invention is of peculiar and novel construction, being open at the bottom to admit the water, having the pair of outlets to register with the supply outlets, and the closed top tormedwith the column and having the seatingfian-ge around the edge of the closedtop, this form ofvalve serving to trap the water and direct it to the service outlets,which is of paramount importance in attaining the highest degree of efficiency.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is 1. In a hydrant, the combination of a casing having outlets and a valve seat, a reciprocating valve seated in the casing, a stem onthe valve and a guide for the stem, a rotary valve having outlet ports for co-action with said outlets and a top to said rotary valve closing it against passage of water, a hollow stem on the rotary valve, a valve rod secured within the hollow stem and projecting below the rotary valve, a joint between the upper and lower endsrespectivcly of the valve stem and valve rod, an annular flange on the lower end of the valve rod, a spider 'frame below the rotary valve, and a spring interposed between. said frame and flange.
